AI Agents aren't magic

Short summary

An AI agent is not magic — it is an LLM combined with orchestration, context, and tools that let it perform actions beyond text generation. The core pattern is a loop that calls the model, checks for tool-call responses, executes matching functions, and feeds results back. The author provides a minimal TypeScript/Node.js agent using Ollama to demonstrate tools, guardrails, and the main orchestration loop.

• •AI agents are LLMs plus orchestration, context, and tool-calling in a loop
• •Tool calls use structured contracts the model fills in and the runtime executes
• •A simple TypeScript/Ollama demo repo illustrates tools, guardrails, and the agent loop
